Gold nanoclusters: Photophysical properties and photocatalytic applications.
Cheng D, Liu R, Hu K. Cheng D, et al. Front Chem. 2022 Jul 19;10:958626. doi: 10.3389/fchem.2022.958626. eCollection 2022. Front Chem. 2022. PMID: 35928211 Free PMC article. Review.
Atomically precise gold nanoclusters (Au NCs) have high specific surface area and abundant unsaturated active sites. Traditionally, Au NCs are employed as thermocatalysts for multielectron transfer redox catalysis. ...

Single-Particle Hyperspectral Imaging for Monitoring of Gold Nanoparticle Aggregates in Macrophages.
Xu L, Wang X, Xu M, Liu S. Xu L, et al. J Phys Chem B. 2023 Apr 13;127(14):3231-3240. doi: 10.1021/acs.jpcb.2c08289. Epub 2023 Mar 30. J Phys Chem B. 2023. PMID: 36995212
However, due to the lack of a rapid, precise, and high throughput method for characterizing Au NP aggregates, the intricate aggregation process of Au NPs has not yet been fully understood. In order to overcome this obstacle, we develop a single-particle hyperspectra …

Deciphering Photochemical Reaction Pathways of Aqueous Tetrachloroauric Acid by X-ray Transient Absorption Spectroscopy.
Liu X, Zhang X, Khakhulin D, Su P, Wulff M, Baudelet F, Weng TC, Kong Q, Sun Y. Liu X, et al. J Phys Chem Lett. 2022 Sep 29;13(38):8921-8927. doi: 10.1021/acs.jpclett.2c02335. Epub 2022 Sep 21. J Phys Chem Lett. 2022. PMID: 36130195
Ultraviolet excitation directly breaks the Au-Cl bond in [Au(III)Cl(4)](-) to form [Au(II)Cl(3)](-) that becomes highly reactive within 79 ps. Disproportionation of [Au(II)Cl(3)](-) generates [Au(I)Cl(2)](-), which is stable for 10 mus. ...

A theoretical exploration of the structural feature, mechanical, and optoelectronic properties of Au-based halide perovskites A(2)Au(I)Au(III)X(6) (A = Rb, Cs; X = Cl, Br, I).
Liu D, Zeng H, Peng H, Sa R. Liu D, et al. Phys Chem Chem Phys. 2023 Nov 1;25(42):28974-28981. doi: 10.1039/d3cp04269c. Phys Chem Chem Phys. 2023. PMID: 37859496
Our calculations indicate that the thermodynamic, dynamic, and mechanical stability of monoclinic Rb(2)Au(I)Au(III)X(6) and tetragonal Cs(2)Au(I)Au(III)X(6) are ensured, and they are all ductile. The electronic band structure analysis shows that Rb(2) …

Here we describe a novel surfactant-directed synthetic route to fabricate mesoAu nanospheres with 3D interconnected mesochannels by using the amphiphilic surfactant of C(22)H(45)N(+)(CH(3))(2)-C(3)H(6)-SH (Cl(-)) (C(22)N-SH) as the mesopore directing agent. C(22)N-SH can not only …

Charge-Transfer-Controlled Quantum Dynamics of HCl Dissociation on the Ag/Au(111) Bimetallic Alloy Surface.
Liu T, Peng T, Fu B, Zhang DH. Liu T, et al. J Phys Chem Lett. 2023 Nov 2;14(43):9713-9719. doi: 10.1021/acs.jpclett.3c02556. Epub 2023 Oct 25. J Phys Chem Lett. 2023. PMID: 37877754
Surprisingly, HCl reactivity is significantly suppressed by the Ag-Au interaction despite a lower HCl+Ag/Au(111) barrier than pure Ag(111). This arises from charge transfer between Ag and Au, where electronegative Au makes the top Ag layer on Ag/Au …
